FullTiltPoints

I got a lot and i want to buy something. I also have rakeback through this site and i know everything i buy from the store will be deducted from my monthly grossed rake. My question is, i buy something that is worth 800 dollar, my monthly grossed rake is 400. Will they take another 400 dollars from my account than?
